Notice Number: NOT-HL-17-546
Release Date: November 3, 2017
National Heart, Lung, and Blood Institute (NHLBI)
The purpose of this Notice is to inform potential applicants that NHLBI will only accept mechanistic studies that meet NIH’s definition of a clinical trial in response to PA-18-345 NIH Research Project Grant (Parent R01 Clinical Trial Required) and its reissues. A mechanistic study is designed to understand a biological or behavioral process, the pathophysiology of a disease, or the mechanism of action of an intervention.
If the proposed research project includes a clinical trial other than a mechanistic study, applicants are strongly advised to contact NHLBI staff to determine the appropriate alternative NHLBI-specific clinical trial FOAs.
